It handles timer-based PWM generation up to the MHz range, UART baud rates beyond 1 Mbps, and SPI clocking fast enough to drive a small TFT display or external ADC. ## Package and footprint — the UFQFN reality The 32-UFQFN package with exposed pad (5x5 mm) is a space-saver but needs careful PCB layout. The 0.5 mm pitch calls for a fine-pitch stencil and good solder-paste registration.","metaTitle":"STM32F031K6U6TR ARM Cortex-M0 MCU, 48 MHz, 32 KB Flash","metaDescription":"STMicroelectronics STM32F031K6U6TR 32-bit ARM Cortex-M0 MCU, 48 MHz, 32 KB Flash, 4K x 8 RAM, 27 I/O, -40°C to 85°C, 32-UFQFPN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"48MHz","Series":"STM32F0","Package":"Tape & Reel (TR) Cut Tape (CT)","RAM Size":"4K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, I²S, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"27","Core Processor":"ARM® Cortex®-M0","Package / Case":"32-UFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 13x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F031","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"32-UFQFPN (5x5)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.0800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7127f169a82fed95ea2bf9d385a9c5f9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F031K6U6TR/alternatives.json"},"ai":{"faq":[{"question":"Is STM32F031K6U6TR compatible with STM32F031K4?","answer":"The STM32F031K6U6TR and STM32F031K4 share the same base product number STM32F031 and the same 32-UFQFN package, so they are pin-compatible.
